Abstract
Assessing uncertainties is a key step towards achieving clarity in decision-making. The assessment of relevant and potentially material uncertainties in a decision context requires a structured approach to characterize the full uncertainty in the situation, avoid cognitive and motivational biases, and ensure a high-quality analysis overall. I discuss the use of relevance diagrams and influence diagrams for deconstructing the uncertainty in a decision situation and facilitating the assessment of each uncertain parameter using a proven five-step process. The method is applied to characterize the uncertainty in a liquefaction capacity investment decision in North America (illustrative case study).
